"Hi, I download a data recovery software for recovery my data from a MacBook. However, it can't find the Macintosh HD where my data is lost. My system is macOS 10.13.2. Anyone knows what happened? Is there any way to recover lost data from Macintosh HD on macOS 10.13 High Sierra?" – Darren
If you are a data recovery software user, you will find that the data recovery software can't find/scan the Macintosh HD or Apple SSD after you upgrade the Mac OS to macOS High Sierra. Why? Because that the new Apple File System in macOS 10.13 does not allow any app to access to the system disk without disabling SIP (System Integrity Protection (SIP) is a security feature introduced in Mac Operating System to restrict the access of third-party applications to system disk and partition. This feature prevents any modification in protected system files and folders on your Mac.).
Normally, the macOS 10.13 is installed on Macintosh HD or APPLE SSD. So, some data recovery programs on the market don't support to recover lost data from Macintosh HD/APPLE SSD on macOS 10.13 High Sierra. Fortunately, there are some Mac data recovery software have been updated for macOS High Sierra data recovery. For example, Magoshare Data Recovery for Mac is one of the software that can help you recover lost data from Macintosh HD/APPLE SSD (also called system disk, startup disk, system hard drive, etc) on macOS 10.13 High Sierra.
